Title Waste heat recovery and utilization by installing heat exchanger to heat recovery steam generator of gas co-generation system
Summaries GHG emission reduction measures : By installing heat exchanger(s) to heat recovery steam generator of gas co-generation system(s), feed water into heat recovery steam generator is heated up. Consequently, consumption of fossil gas fuel by duct burner is reduced, leading to the reduction of GHG emissions.
Calculation of reference emissions : Reference emissions are calculated using amount of fossil gas fuel consumed by duct burner of heat recovery steam generator with project heat exchanger, density of fossil gas fuel consumed by duct burner of heat recovery steam generator, net calorific value of fossil gas fuel consumed by duct burner of heat recovery steam generator, CO2 emission factor for the fossil gas fuel consumed by duct burner of heat recovery steam generator, amount of heating energy recovered by project heat exchanger and amount of heating energy transferred into the feed water of the heat recovery steam generator with project heat exchanger.
Calculation of project emissions : (In case that project additionally consumes electricity) Project emissions are calculated with electricity consumption of pre-treatment equipment(s) and CO2 emission factor for electricity consumed.
Monitoring parameters : Amount of fossil gas fuel consumed by duct burner of heat recovery steam generator with project heat exchanger; Flow rate of feed water into project heat exchanger; Temperature of water at the outlet of project heat exchanger; Temperature of water at the inlet of project heat exchanger; Flow rate of feed water into heat recovery steam generator with project heat exchanger; Temperature of feed water into heat recovery steam generator with project heat exchanger; Amount of electricity consumed by the project
